MAX6336US23D3+T

Overview

The MAX6336US23D3+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.0V to 5.5V and features a fixed threshold voltage of 2.3V. The device provides an active-low reset output with a minimum timeout period of 140ms. It is housed in a compact SOT-143-4 surface-mount package and supports an extended operating temperature range from -40°C to +125°C.

Feature Summary

• Provides reliable system reset during power-up, power-down, or brown-out conditions
• Features a manual reset input for software-initiated system resets
• Includes a battery backup pin to maintain reset assertion during low-voltage states

Applications

• Microprocessor and microcontroller power supervision
• Portable battery-operated electronic devices
• Industrial control systems requiring wide temperature operation

Procurement Notes

Verify the specific suffix D3 against official documentation to confirm the 2.3V threshold and 140ms timeout parameters. Confirm RoHS compliance status and check current availability as distribution channels may list obsolete or limited stock variants. Ensure the SOT-143-4 package matches your PCB footprint requirements before ordering.

Selection Notes

Select this component when a fixed 2.3V monitoring level is required for low-voltage logic families. The inclusion of a manual reset pin and battery backup support distinguishes it from simpler supervisor ICs. Verify that the 140ms typical delay meets the timing constraints of the target processor's startup sequence.

Part Context

This part belongs to the MAX6336 family of ultra-low-power microprocessor supervisors. The series offers various threshold voltages and timeout periods packaged in small form factors like SOT-143 and SOT-23. The US23 variant specifically denotes the SOT-143-4 package with a 2.3V threshold.

Replacement Considerations

Cross-reference with MAX6336US23D2+T for similar functionality but verify if the timeout characteristics differ. Check MAX6336US23D3+ for non-tape reel packaging options if available.
